Product Introduction

Overview

The HMC908ALC5TR-R5, produced by Analog Devices Inc., is a compact gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) designed as an in-phase/quadrature (I/Q) downconverter. This device is optimized for microwave radio applications, particularly in the frequency range of 9 GHz to 12 GHz. It features a leadless, RoHS-compliant ceramic leadless chip carrier package, making it a smaller and more efficient alternative to traditional hybrid style image rejection mixer downconverter assemblies.

Key Features

  • Compact Design: The HMC908ALC5TR-R5 is designed in a compact, leadless package, making it ideal for space-constrained applications.
  • Image Rejection Mixer: The device includes an image rejection mixer that eliminates the need for a filter following the low noise amplifier (LNA), reducing thermal noise at the image frequency.
  • I/Q Mixer Outputs: Provides separate I and Q mixer outputs, requiring an external 90° hybrid to select the desired sideband.
  • Low Noise Amplifier (LNA): Self-biased LNA with a bias current of 53 mA at 3 V.
  • LO Driver Amplifier: Self-biased LO driver amplifier with a bias current of 100 mA at 5 V, compatible with Analog Devices’ wideband synthesizer portfolio.
  • Wide Frequency Range: Supports a wide range of RF and LO frequencies, making it versatile for various microwave radio applications.

Applications

The HMC908ALC5TR-R5 is optimized for point-to-point and point-to-multipoint microwave radio applications. It is particularly suited for systems requiring high image rejection and low noise figures, such as in wireless communication infrastructure, satellite communications, and radar systems.
